lND-EX-TAB.

SPECIFICATION forming part of Letters-Patent No. 508,289, dated November 7, 1893. Application filed November 18, 1892. Serial No. 452,396. (No model.)

' useful Improvement in Index-Tabs, of which the ordinary manner.

the tab is suppcsedto'be made of an outside,

. a, of leather or other material suitable for the following is a full, clear, and exact description.

My improvement relates more especially to the means for protecting, stifiening, and ornamentlng an lndex tab, or analogous construction, substantially as is hereinafter set forth and claimed, aided by the annexed drawlngs, making part of this specification, in

which 7 Figure 1 is a face View of a development of the tab; Fig. 2 an edge elevation of the same; Fig. 3 an edge elevation of the tab partly folded; Fig. 4 a View in perspective of the frame, border, or guard which is applied to the tab; Fig. 5 a face view of the tab having the frame applied thereto; Fig.6 a section on the line 6' 6 of Fig. 5; Fig. 7 a section on the line 7-7 of Fig. 5; and Fig. 8 a View showing the improved tab in position upon the leaf.

The same letters of reference denote the same parts. i

The tab, A, in itself is of the usual construction, and it is applied to the leaf, B, in In the present instance tabs, and an in'side',-a-, of some textile fabric which is cemented to the inner side of the part a forthe purpose of strengthening the construction and enabling it to be desirably applied to the leaf. 7 Y

0 represents what may be termed a frame, border, or guard. Its function primarily is to protect that portion of the tab which projects from the leaf from wear. It also serves to materially strengthen the tab,'and

to preserve its form, and it may be utilized to enhance the appearance of thetab. Its most desirable form is shown. It is composed of any suitable material for the purpose in question, and preferably of thin sheet metal, and generally one whose color contrasts with that of the tab. It is preferably arranged directly at the edge of the tab as shown, and it is, in the present instance, adapted to the tab by making it in the form of a grooved or folded piece of metal shaped to fit onto the edge of the tab, and it is secured to the tab in any suitable manner and usually by compressing the folds, c, c, of the frame closely onto the faces of the tab, and in providing forthe proper connection of'the frame with the tab the two parts may have any preferred relative shape so that they may be interlocked, connected, or'secured together in any desired manner. The part, 0, when thus attached to the tab forms projections upon the faces of the tab which take a large portion of the wear which otherwise comes directly upon the tab in use. The letter, D, or whatever character is upon the tab, is therefore rendered more durable. The frame also aids to preserve the form of the tab, and to keep it in position. When properly applied the frame is made to meet the edge of the leaf, substantially as shown in Fig. 8.

I claim- 1. As a new article of manufacture anindex tab for book leaves, provided at the edges of one endwith a protecting and stiffening frame, substantially as described.

2. An index tab for book leaves lined on the inside with textile material to enable it to .be attached to the leaf, and provided at the-end projecting beyond the leaf edge with a strengthening and protecting frame, substantially as described.

Witness my hand this 12th day'of November, 1892.

OTTO, J. DEOKELMANN.
